I think im gonna install a hands free 2 way radio in my helm. My brother wants to make Mjolnir also I've made a Mock Helmet and a right leg piece out of paper for sizing I think the helm little too big.Today I started my actual helm and am still on the top of it ive glued about 12 pieces on. So far so good. But anyway you can purchase these hands free 2 way walkie talkies at toy stores on line google under spy stuff. I think itll give us an advantage for paintball.
